SUSPENSION-SLEEVE FOR MESH-MACHINES.

Specification of Letters Patent.

Patented Nov. 15., 1921.

Application filed January 3, 1921. Serial No. 434,772.

To all to ham it may concern Be it known that I, SAHATIEL G. MAN-DALIAN, a citizen of the United States, residing at North Attleboro, inthe county of Bristol and State of Massachusetts, have invented certainnew and useful improvements in Suspension-Sleeves for Mesh-Machines, ofwhich the following is a specification.

My invention relates to a device adapted for use in a mesh machine forreceiving the initial row of units previously formed, and for carryingsaid row of units during the attachment of subsequent rows of units insuch a manner as to produce a mesh. When a mesh machine has the initialunits presented to it in a row arranged to receive subsequent rowsthereon, the machine is sometimes called a mesh machine. Two suchmachines and the mesh formed thereby are shown in U. S. Patents No.948,615 issued. February 8, 1910, to Pratt, and No. 1,139,? 99 issued toPratt, March 18, 1915.

In such machines the operation was not wholly automatic because asuspending or receiving device was lacking, and it was necessary to makeby hand a long initial broad strip of flexible mesh fabric forsuspension on the mandrel to present a row of units to the formingtools. This strip had necessarily a more or less irregular and roughsurface which prevented regular movement upon the suspension anvil, withconsequent breakage and delay in machine operation.

The essential objects of my invention are to overcome the enumerateddisadvantages attendant upon the absence of a suspension device, andprovide a device which will enable mesh machines to operate whollyautomatically.

To the above ends essentially my invention consists in such iarts and insuch combinations of parts as fall within the scope of the appendedclaims.

In the accompanying drawings which form a part of this specification-Figure 1 is a plan view partially in section of the anvil and certainparts adjacent thereto of one usual form of mesh machine in which mydevice is mounted,

Like reference characters indicate like parts throughout the views.

In the drawings 11 represents the hollow post or mandrel of a usual meshmachine havlng the thread 12 upon its upper portion and carrying thereciprocating radially arranged dies 13. Two sets of forming toolscooperating with'the dies are shown, alike in all respects, anddiametrically oppositely disposed. A description of one set serves forboth. 15 is one of the guide blocks supporting the plunger 16cooperating with the die 13 and carrying the reciprocating die rod 17and sleeve 19 with its prongs 20. 21 is the transversepassage for theintermittently fed wire. The bell crank lever 23 carries the forminganvil 24 and is engaged by the reciprocating plunger 25. 27 is the fixedsupporting ring carrying loosely the sleeve 28 with its internalvertical ridges 29, and external ratchet teeth 80, engaged by pawl 32pressed by spring 33 in rock shaft 34. The sleeve 28, which is advancedstep by step by the pawl and shaft the distance of a. tooth, is retainedby the pawl 86. The ridges or thread 12 of the mandrel and the ridges orribs 29 of the sleeve 28 cooperate with the shallow depressions in thesurfaces of the finally manufactured mesh sleeve located therebetween sothat the rotation of the sleeve 28 will cause the mesh sleeve to moveupwardly with itself on the mandrel being simultaneously attached.

' series of longitudinally disposed grooves 43 and ribs 44adapted toslidably interengage the ridges 29. of the operating sleeve 28. The ribs44 have preferably transversely inclined. faces appearing in transversesection as if they were ratchet teeth. The lower portion of the sleeve39, as at 45, is preferably smooth and of reduced thickness. he loweredge of the member 39 is preferably inclined at an angle corre spendingwith the inclineof the spiral threadm' groove 40 and is interrupted atdiametrically opposite points by rounded vertical shoulders 46 and 47forming. two inclined edge sections 49 and 50. The number of theseshoulders is determined bythe number of sets of forming tools. In thiscase two sets of forming tools are supposed to be employed, and two rowsof rings are The shoulders are in depth about the radius of one of therings of the mesh to be formed. Ad-

jacent the edges of sections 49and 50 respectively are series ofequispaced holes 53 and 54. The portions 49 and 50 respectively of thesleeve 39 are preferably slightly out- \vardly and inwardly inclinedrespectively at their lower edges as shown at 57 and 58 in Fig. 7. V

The rings are formed by the described forming tools in the usual manner.The two sets of tools are diagrammatically indicated in Figs. 9 and 19by a and b, which respectively initially form and insert the rings 61and 62 in the series of holes 53 and 54 and thereafter as the sleeve 39revolves form continuous rows of intermeshing links, each spiral rowhaving the links angularly disposed relativelyto each other. It will beobserved that in this case the rings 62 depend within the sleeve 39, andthe rings 61 depend exteriorly of the sleeve. The angular relation ofthe link rows is assistedby the inclines of the sleeve portions 49 and50.

As the mesh formed on the device 39 grows in length the latter graduallymoves upwardly upon the anvil until it is free therefrom whereupon themesh is manually severed from the sleeve, and its place is taken by themesh severed therefrom now in the machine.

I claim 1 In a mesh machine, a mandrel, a feeding sleeve rotatablymounted around the mandrel, and a rigid suspension sleeve en gaging themandrel and the feeding sleeve.

2. In a mesh machine, a mandrel provided with a thread, a stiffsuspension sleeve provided with a thread loosely engaging the firstthread, and means for rotating the suspension sleeve.

3. In a mesh machine, a mandrel provided with a thread, a feeding sleeverotatable around themandrel provided with internal vertical grooves, anda rigid suspension sleeve provided with an internal thread looselyengaging thefirst thread, and external vertical ribs slidable in thegrooves.

4. In a mesh machine, a mandrel provided with a thread, a suspensionsleeve provided with 'a thread engaging the first thiead, and verticallydisposed transversely inclined ribs upon the exterior of the suspensionsleeve. 7

5. In a mesh machine, the combination with a mandrel and feeding sleeve,of a stiff suspension sleeve loosely engaging the mandrel and thefeeding sleeve and provided at its lower end with series of marginalholes. 7

6. In a meshmachine, a mandrel, a feeding sleeve, a stiff suspensionsleeve engaging the mandrel and sleeve, and provided at its lower endwith an inclined edge and with an inclined series of. marginal holes.

7. In a mesh machine, a mandrel, a stiff suspension sleeve mounted onthe mandrel provided upon its lower edge with vertical shoulders andwith the portions of the edge intermediate the shoulders inclined, andprovided with inclined series of marginal holes adjacent the inclinededge portions.

8. In a mesh machine, a mandrel, a stiff suspension sleeveloose on themandrel provided upon its lower edge with depending shoulders and havingthe portions of the sleeve intermediate the shoulders laterally inclinedinwardly and outwardly, said intermediate portions being also providedwith series of marginal holes.

9. As an article of manufacture, a suspension sleeve for ring meshmachines comprising a cylindrical body provided with a smooth lowerportion and with an internal thread above the smooth portion, verticalexternal ribs above the smooth portion, said smooth portion beingprovided with depending shoulders and inclined edge portions between theshoulders,and with series of marginal holes.

In testimony whereof I have afiixed my signature. 7 if SAHATIEL e.MANDALIAN.
